Vehicles do not load any cargo after some decades of game time

[Tarlek]

Hi!

I'm playing Simutrans 124.2 pak64. I noticed that, after playing for some decades (game time) the new industries that pop up do not load any goods. They're fully connected to their consumers, the vehicles are of the right type, the consumer industries are empty... but the vehicles simply stay in the cargo bays and do not load anything.

What's odd is that this starts to happen after 40-50 years of game time. I was wondering if there's a limit in the number of vehicles or in the amount of cargo that can be transported at a given time, or something like that (after 40-50 years there're probably many hundreds of vehicles transporting goods all over the map).

I'm linking some screenshots of an industry chain with a timber plantation and a saw mill. They're connected, the saw mill is empty, the plantation produces wood but the trucks in the cargo bay refuse to load any lumber.

Any idea of what could be happening? Am I missing something?

Thanks!

I think the key is in your second image. In the sawmill there is the consumption:

wood: 0/0(3136)/587 m3

I always get confused by these numbers, but it is something like:

There is 0 m3 wood stored in the sawmill
There is 3136 m3 wood designated to go to the sawmill, of which 0 m3 is really underway
There is a maximum of 587 m3 wood storable in the sawmill.

Now, in the settings there is a something like

just_in_time = 2

This means that if a lot of wood is designated to go to the sawmill it will stop transporting (and designating?) them. If you put that on

just_in_time = 1

it stops transporting when the actual available wood (the first 0) in the sawmill is bigger than the capacity (587).

If you put that on

just_in_time = 0

it never stops transporting.

I personally prefer just_in_time = 1, just for the reasons you are seeing now, the sawmill is not producing anything.

If you change this setting, you might have to restart your game (or Simutrans itself) to get any effect, but it should work eventually.

Hope this helps and maybe someone can correct me if I stated something wrong.

Just_in_time = 2 has some special behave. Maybe you could also call it bugs.

If you overfill the input store, then the goods that don't fit, are thrown away.
But the production stop until the thrown away goods are consumed virtually.

If this is the case, you can test it. Just let it run with fast forward.
Maybe it takes some year, but suddenly the production starts again on its own.
Watch if the input store becomes overfill again.

124.2 is seriously broken in later game states. Please update.

I fiddled with the just_in_time parameter with no success. I eventually updated to 124.3 and the problem was fixed. Now the vehicles load the cargo in all industries, new and old.

Thanks for your replies!
